Cadillac Repair: 1999 STS Heated Seat, volt ohm meter, digital volt ohm meter

Question
Hi there, I have a 1999 STS, my driver side heated seat does not work. I know for a fact that the switch works because I flopped the driver and passenger side wires and the drivers switch worked the passnegers heated seat when I did that. I know for a fact that the heated seat pads are working because I just bought them brand new from a dealer, butt and back. The wires are hot all the way down to the "heated seat controll unit" which is where all the wires for it run to. There are 2 hot wires going into the heated seat controll unit, I assume one is a high setting wire and one in the low setting wire. So my question is, is it the heated seat conroll unit? The way I see it thats what it has to be, but your the expert any ideas would be very helpful. Thanks for your time!

Answer
The ONLY way to determine what is at fault is to perform simple test procedures using a DIGITAL VOLT/OHM METER which you can purchase at Wal-Mart for $20.00 or at any auto parts store.
